Do you get an unclean feeling when you look at the tile while you prepare for food in the kitchen or while you bathe your children in the bathroom?
If you do, you are probably right; it is unclean. But it’s not your fault. Most tiles are installed with the grout unsealed. Unsealed grout slowly absorbs foods, liquids, and dirt, and it is impossible for household cleaners to pick up all of them. The remaining contaminants will accumulate over time and grow germs, make it look dirty, and give you that unclean feeling.
We use the best professional tile & grout cleaning products on the market along with heated, high pressure and vacuum cleaning machines to remove the residue. 
Then we can seal the grout so that it will be protected. Also, if you would like to get a new look for your tile, we can use a colored sealer of your choice.
